Question

when an object falls freely to the ground its acceleration is uniform give scientific reason
plz plz answer the question ​

Answer 1

Explanation:

When a body is falling freely then the only force acting on it is gravitational force by the Earth .(assuming of course that the body is on earth.)

now since the force of gravity is consistent i.e it does not change.(change is negligible)

since F=ma (by Newton's second law)

force is constant ,mass is anyway constant , so the acceleration gained by the body must also be constant. i.e it's uniform.

hence we can say that a free falling body experiences a uniform acceleration.

that happens to be 9.8 m/s²(approx.)

Answer 2

Answer:

This is because of gravitational force of earth.
